Gamma Progression 200 - New Stringer

I bought "Gamma Progression 200" last week and did my 1st stringing (2-piece) yday with BLX JUICE 100.
I'm going to hit with it today evening but I have question

1. when I tighten the last main(10T) and clamp (came with the machine) it with 8T(SKIP 9T) I have trouble clamping as the string tends to bend because of huge gap between 8T & 10T.
Is this how it should be?
Also, i feel like i lost the tightness in the last mains due to this and a bit while tie-off.
Can somebody explain how to handle this part of stringing?

OK this won't be as good as the triple clamp but better than what you're doing I think. When your string the 7th main on one side hold it on the outside the frame with a starting clamp. This frees up the flying clamp on that side. When you finish the mains on the other side instead of just using one clamp to hold the outside main use both as near together as you can get them. Less twisting that way. After tying off one side repeat on the other.
